背景技术Background technique
扫路车工作时，由风机安装系统运转提供地面垃圾吸纳、提升所需的真空负压，由发动机带轮通过皮带带动风机运转，而皮带在使用过程中需要一定的张紧力才能正常传递动力，因此，皮带传动通常都需要相应的张紧装置。常见的张紧装置在皮带发生伸长变形时，张紧力会很快减小而无法正常传递动力，需要人工及时调整带轮的位置以压紧皮带获得足够的张紧力，本装置实际工作中传递的动力很大，皮带的变形和人工调节都过于频繁。因此，在扫路车风机安装系统的大功率皮带传动中，需要尽可能减少带轮张紧力的人工调节次数以提高扫路车的整车性能。When the road sweeper is working, the fan installation system operates to provide the vacuum negative pressure required for ground garbage absorption and lifting, and the engine pulley drives the fan to run through the belt, and the belt needs a certain tension during use to transmit power normally. , Therefore, belt drives usually require corresponding tensioning devices. In common tensioning devices, when the belt is elongated and deformed, the tension will decrease quickly and the power cannot be transmitted normally. It is necessary to manually adjust the position of the pulley in time to compress the belt to obtain sufficient tension. This device actually works The power transmitted in the belt is very large, and the deformation and manual adjustment of the belt are too frequent. Therefore, in the high-power belt drive of the road sweeper fan installation system, it is necessary to reduce the number of manual adjustments of the pulley tension as much as possible to improve the overall performance of the road sweeper.
